CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 299,599, dated June 3, 1884-.

Application led October 20, 1883.

To all whom, it may concern Be it known that I, IsAAC H. TRABUE, a citizen of the United States, residing at Louis ville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Car-Couplings; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to that class of earcouplers in which the pin is made to auto matically drop by the link operating on certain mechanism, and particularly relates to an improvement upon the device shown and described in an application filed by me July v3, 1883; and it consists of constructions and combinations, all as willhereinafter be described and claimed, reference being had to the accompanying drawings, in which- Figure 1 represents a longitudinal section through two draw-heads; Fig. 2, a perspective of the pendulum and bolt; and Fig. 3, a coupling-pin, having its lower end in section to s how a recess or depression in the same.

A A represent the draw-heads; B, the'link; C, the pins, and D the pendulum. rIhe drawheads are provided with openings a, preferably formed obliquely to the plane of the top of the draw-head and vertical pin-holes .or openings c. Suspended from the top of the draw-head by a pin or nut, ci, is a bolt, A3, which passes through the opening a in the draw-head and projects into the space for the link. The end of this link is slotted at ai, to give vertical play to the 4pendulum D, which is supported therefrom by a pintle, a, passing through ears d. The pendulum is recessed at d', to form a projection, di, for supporting the pin C, which is provided with a recess, c, that embraces said projection d2. Ihe front of the pendulum is dished at d, and has lateral grooves d", which conform in intaglio to the shape'of the end of a link, except that the walls are made more flaring. The form of said groove is similar to a U, as may be seen in Fig. 2. The ob-- ject of this construction is to hold the link in such a position (see Fig. 1) that the free end will pass into the draw-head of the car to be coupled without any other guidance, and allows the link to be lifted or moved to any desired position. The frontal projection, d, adds strength to projection cl2, and

(No model.)

Y its lower end d6 serves as a hook to irevent the link from sliding from the draw-head when in position to be coupled. rIhe back of the pendulum is provided with an inclined face, d, to which the ears d' are attached, and a rounded part, (ZB, which conforms to the shape of the end d of the link-space, so that when forced back the pendulum will have a free space to swing in and an even surface to strike against, which will prevent breakage. The ears dl project into a space, a, in the draw-head. This space is of greater depth than the ears, so that the pendulum can move freely in the slot a3, which permits the lower end of the pendulum to rest upon the door of the link-space, and thus presenta firm support for the pin C,

The operation of the device is as follows: The link is shoved in one of the draw-heads and the pin dropped in its hole, as shown at the right of Fig. 1. The pin in the second draw-head is inserted through the upper opening and the recess in its end embraces the projection d2. One of the vcars is moved toward the other until lthe free end of the link strikes the pendulum in the draw-head and forces it back until the pin is released from projection d? and drops through the link into the lower pin-hole.

Vhat I claim as new is- 1 1. In a coupling, the combination of a swinging pendulum having a projection immediately under the pin-hole, and a pin having a recess in its lower end, substantially as described.

2. In a coupling, the combination of a bolt having a slotted end, and a pendulum suspended from said bolt by a pintle passing through said slot, substantially as described.

3. In a coupling, the combination of a drawhead having a bolt-hole,abolt passing through said hole and having a slotted end, and a pendulum having ears connected with said bolt by a pintle, which passes through said slot, substantially as described.

4. In a coupling, a pendulum having a U- shapedgroove, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

ISAAC H. TRABUE.
